The reactor anti-neutrino experiments; Daya Bay, Double Chooz and RENO, have been incredibly successful. Since the first hint of theta_13 in 2011, which was larger than expected, the value of sin^2(2theta_13) has been now measured by the three experiments to be 0.084 +/- 0.005, 0.09 +/-0.03 and 0.101 + 0.013 respectively. I will describe the experiments, highlighting the main differences between them, and review the different and complementary methods of obtaining theta_13 (rate, spectrum, rate modulation, and hydrogen capture). I will show the latest results and the projections of the expected final sensitivities. Other measurements can also be made with reactor experiments, such as delta_m^2ee, search for sterile neutrinos, and comparisons of the anti-neutrino spectrum to reactor models. I will briefly summarise these additional results.
